Controlled Motion Exercise Device

ABSTRACT

An exercise apparatus includes a frame, one or more pull cables running through cable guides to provide resistance exercise, and a mechanism for providing variable resistance to the cables. The frame may include a pair of uprights and a pair of cross members that combine to form a rectangular construct that allows the cable guides to be mounted at a multiplicity of selected points above and to both sides of a user standing between the uprights. The guides may be mounted at any of the selected points on the uprights and the cross members to allow the user to select an advantageous “pull point” for a desired exercise without moving the frame members and without moving other guides. A computer/processor may be used to control the resistance force applied to the cables and/or to record exercise results.

FIELD OF THE INVENTION

The present invention relates generally to exercise equipment, and moreparticularly to exercise equipment with controlled velocity orcontrolled range of motion.

BACKGROUND

Many exercises for therapy, sports, recreation or body-building involvethe use of free weights. Free weights are held in the hand and movedalong predetermined trajectories to exercise specific muscle groups. Themotion is repeated for a specific number of times. However, it isdifficult to precisely follow a predetermined trajectory for eachrepetition. It is also difficult to maintain a smooth and controlledmotion. Abrupt loss of control may injure muscles. In certain strenuousexercises involving relatively heavy free weights, the repeated motionand weight can impact muscle groups other than those intended to beexercised, leading to injury and bruises. A heavy free weight held inthe hand intended to exercise chest muscles may exert an unintentionalheavy load on the knees. Free weights are also associated with dangersto other individuals exercising in the vicinity in case of loss ofcontrol. If a free weight falls from an individual's hand it may hurtother individuals.

Some exercise machines have been developed to overcome disadvantagesassociated with free weights and permit safe exercising. These exercisemachines involve the use of adjustable weights loads enclosed in aframe, which are connected through pulleys, gears and cables to framesand handles. The user exerts force on the handles and frames, and thecables transmit the load of the weight to the user. This may reduce someof the dangers associated with free weights.

However, these exercise machines are expensive. Many of them aredirected to exercising specific muscle groups. Further, these machinesoften have a limited adjustability and the configuration of use islargely fixed. It is difficult to use the same machine in differentconfigurations. A machine devised for a healthy individual exercising ina gym may not be suitable for a hospitalized individual who is unable tomove from his or her bed. A machine devised for exercising the thighsmay not be useful for exercising the forearms.

The motion of free weights or the weights in exercise machines moveaccording to the laws of gravity. When these weights are moved along atrajectory, they always exert a force component in a downwardsdirection. When a free weight is lifted, the part of the trajectory inwhich the weight is moved against the ground is controlled by theindividual. However, in the final part of the trajectory, the weightmoves towards the ground. In this part of the trajectory, the forceexerted at every point of the trajectory against the user's muscles isuniform and dictated by the weight. In case of the exercise machines theforce exerted is always uniform and depends on the selected weight orload.

This makes maintaining a uniform velocity throughout the trajectory verydifficult for individuals. An individual may be able to move the weightwith a controlled velocity for a part of the trajectory but may losecontrol, leading to a rapid velocity change. Such unintended velocitychanges along the trajectory of motion of free weights or weights inexercising machines can cause short-term or long-term injuries to theuser.

Certain exercises need the velocity of motion along the trajectory andexerted force to vary in a predetermined manner along the trajectorypath of motion of the exercise equipment.

A need exists for a low-cost and flexible exercise machine that allowscontrolled motion exercise of various different muscle groups. A needalso exists for an exercise machine that ensures the safety of theexercising individual and the safety of other individuals in thevicinity of the exercising individual. A need also exists for a machinethat can be used by users who may not have full control over theirbodies. A need also exists for an exercise machine that can be used byusers in various positions such as standing, sitting or lyinghorizontally. A need also exists for a machine that exerts force varyingalong the trajectory of motion of exercise in a predetermined manner. Aneed also exists for a machine that allows exercising parts to movealong a specified trajectory with a velocity that varies along thetrajectory of motion in a predetermined manner. Various aspects andembodiments of the present invention are intended to address one or moreof these needs.

In another embodiment, HOOPS 128 are secured to HOOP SLOTS 124 bynut-and-bolts or any other fasteners.

A COILING MECHANISM 132 may be secured to the BASE 104. The COILINGMECHANISM 132 allows a CABLE 136 to be wound on it. In an embodiment,the COILING MECHANISM 132 contains a spring or similar elastic elementthat retracts the CABLE 136 when not in use.

CABLE 136 has two ends, a WINDING END 140 and an OPERATING END 144. TheWINDING END 140 of the CABLE 136 is wound on the COILING MECHANISM 132.

To prepare the CONTROLLED MOTION EXERCISE MACHINE 100 for a particularexercise, the user or trainer passes the CABLE 136 through a GUIDEPULLEY 146 and one or more HOOPS 128 such that the OPERATING END 144 ofthe CABLE 136 is free to be engaged by the user when the exercisebegins.

In the embodiment if FIG. 1, a ROBOTIC MOTOR 148 is secured to the BASE104. In another embodiment, the ROBOTIC MOTOR 148 is contained in amotor housing secured to the base 104. In an embodiment, the ROBOTICMOTOR 148 is coupled to the COILING MECHANISM 132 through a GEAR SYSTEM156. The ROBOTIC MOTOR 148 turns the COILING MECHANISM 132 such that theCABLE 136 is wound or unwound according to the exercise on the COILINGMECHANISM 132. In an embodiment, the ROBOTIC MOTOR 148 is controlled byelectronic impulses sent by a COMPUTER CONTROLLER 158. The COMPUTERCONTROLLER 158 may be a laptop, a desktop computer or a portablecomputer or any other computing device. In another embodiment, theCOMPUTER CONTROLLER 158 is connected to the ROBOTIC MOTOR 148 through aPOWER AMPLIFIER 160 in a feedback loop. The POWER AMPLIFIER 160amplifies the electronic impulses sent by the COMPUTER CONTROLLER 158.In an embodiment, the feedback loop allows the COMPUTER CONTROLLER 158to sense the operation of the ROBOTIC MOTOR 148 in response toelectronic impulses and force exerted on the CABLE 136 by the user. Inanother embodiment, the feedback loop also allows the COMPUTERCONTROLLER 158 to receive information about the load or force exerted onthe ROBOTIC MOTOR 148 through the GEAR SYSTEM 156 by the CABLE 136.

The user exerts a force or load on the CABLE 136 against the forceexerted by the ROBOTIC MOTOR 148 to exercise target muscles. A userselects an exercise through the COMPUTER CONTROLLER 158. The COMPUTERCONTROLLER 158 selects a program of electronic impulses and sends theseelectronic impulses determined by the exercise selected by the user tothe ROBOTIC MOTOR 148 through the POWER AMPLIFIER 160. The ROBOTIC MOTOR148 begins to wind or unwind the COILING MECHANISM 132 as directed bythe electronic impulses. The COILING MECHANISM 132 either retracts theCABLE 136 at a predetermined velocity or allows the CABLE 136 to beextended at a predetermined velocity depending on the exercise chosen bythe user using the COMPUTER CONTROLLER 158.

The user exerts load or force on the OPERATING END 144 of the CABLE 136against the force applied by the ROBOTIC MOTOR 148. The ROBOTIC MOTOR148 senses the force exerted by the user on the CABLE 136 and operatessuch that the CABLE 136 moves at a predetermined velocity regardless ofthe force exerted by the user, resulting in a controlled motionexercise.

In one embodiment, the COMPUTER CONTROLLER 158 continuously monitors theforce exerted on the ROBOTIC MOTOR 148 by the user. The COMPUTERCONTROLLER 158 directs the motion of the CABLE 136 by sending electronicimpulses to the ROBOTIC MOTOR 148 in response to the force exerted bythe user so that the CABLE 136 moves in accordance with the exercisechosen by the user.

The HOOPS 128 guide the motion of the CABLE 136 along a path appropriatefor the exercise chosen by the user so that the motion of the cableresults in the application of force in a predetermined direction suchthat specific muscle groups are exercised without harming the othermuscles of the user.

In one embodiment, an ERGONOMIC GRASP 164 is be connected to theOPERATING END 144 of the CABLE 136. In various embodiments, theERGONOMIC GRASP 164 is in the form of a rod, a handle, a ball, or anyother form that is useful for particular exercises. In an embodiment,the ERGONOMIC GRASP 164 is shaped like a ball for exercising baseballpitching movements. In another embodiment, the ERGONOMIC GRASP 164 isshaped like a staff for facilitating rowing exercises.

In one embodiment the ROBOTIC MOTOR 148 is connected to two CABLES 136,and with the ERGONOMIC GRASP 164 in the form of a rigid staff secured toboth CABLES 136, such that pulling on the staff engages both CABLES 136simultaneously. In yet another embodiment, the OPERATING ENDS 144 of twoCABLES 136 can be connected by an ERGONOMIC GRASP 164 in the form of along rod or a staff, for martial arts or other exercises. In variousembodiments, the ERGONOMIC GRASP 164 is made of materials such as metal,rubber, plastic, wood or any other material suitable for a particularform of exercise. In an embodiment, the ERGONOMIC GRASP 164 has a shapesuitable for physical therapy. In another embodiment, the ergonomicgrasp 164 is shaped such that a trainer can assist the exercising userin exerting force.

In one embodiment, the ERGONOMIC GRASP 164 is connected to the OPERATINGEND 144 of the CABLE 136 by a FLEXIBLE CONNECTOR 170. In variousembodiments, the FLEXIBLE CONNECTOR 170 contains springs, rubber cables,elastic bands, rubber bands, or other flexible elements. The FLEXIBLECONNECTOR 170 allows the user to get non-linear play in the motionsuperimposed on the predetermined velocity of the CABLE 136 controlledby the ROBOTIC MOTOR 148. This allows the user to exert slightly higheror lower forces on the cable without facing sudden velocity changes thatcan result in injury.

The Examples given above are merely illustrative and are not meant to bean exhaustive list of all possible embodiments, applications ormodifications of the invention. Thus, various modifications andvariations of the described methods and systems of the invention will beapparent to those skilled in the art without departing from the scopeand spirit of the invention. Although the invention has been describedin connection with specific embodiments, it should be understood thatthe invention as claimed should not be unduly limited to such specificembodiments. Indeed, various modifications of the described modes forcarrying out the invention which are obvious to those skilled in thechemical arts or in the relevant fields are intended to be within thescope of the appended claims.

In another preferred embodiment of the present invention there isprovided a controlled motion exercise device that includes a frame, oneor more cables for the user to pull to provide resistance exercise, anda mechanism for providing variable resistance to the cables.

The frame may comprise a pair of uprights and one or more cross members,optionally mounted to a base. The uprights are preferably spaced between36″ and 96″ apart to allow a user to mount cable guides on both sides ofthe user's body when the user is positioned near the center of theframe. More preferably the uprights are spaced between 36″ and 72″apart.

At least one of the cross members is preferably positioned at a heightof between 60″ and 120″ to allow a user to mount cable guides well abovethe user's head when the user is positioned near the center of theframe. In one preferred embodiment there are two cross members mountedat varying heights to the pair of uprights. In such embodiments, thesecond cross member is preferably positioned at a height of between 12″and 60″, and more preferably at a height of between 24″ and 48.″ Thecross members are preferably horizontal with respect to the base.

A plurality of positions for mounting a cable guide to the frame areprovided on each of the pair of uprights, and on one or more of thecross members. Such positions for mounting a cable guide preferablycomprise slots that are sized to receive the shank of a cable guide asdescribed below. The slots provide discrete locations for mounting acable guide shank, with such locations preferably being between 6″ and12″ apart (preferably about 8″ apart) along at least a portion of eachupright and along at least one cross member.

A plurality of cable guides are preferably mounted to the uprightsand/or the cross members. The cable guides are adapted to allow a pullcable to pass therethrough, thus providing one or more “pull points”from which the resistance on the pull end of a cable may be applied. Theguides may be mounted to any of a plurality of points on the uprightsand/or the cross members to allow the user to select an advantageouspull point for a desired exercise. When multiple guides are provided onthe frame, and particularly when those guides are mounted to differentuprights and/or different cross members, the user may independently pulltwo or more arms and/or legs simultaneously, with the two or more armsand/or legs meeting resistance from different pull points which may beon different sides of the user's body.

The cable guides may comprise an eye or a hoop that is provided on theend of a shank. In one embodiment the cable guides comprise a pulley onthe end of a shank. The pulley allows the cable to pass through theguide with less resistance than is provided by a hoop or an eye.

The cable guides are mountable to one or more of a multiplicity ofmounting positions on the frame by providing the frame with a pluralityof slots adapted to receive the guide shanks. This allows the user toquickly and easily change the pull point of a particular cable, and alsoallows such change to be done without also changing the position of theuprights and/or the cross members, and without changing the locations ofthe pull point of other cables that may be being used at the same time.The user simply pulls the cable guide shank from one slot and pushes itinto a different slot without requiring the cable or the frame to beadjusted.

Each cable comprises a pull end and a winding/coiling end, and a lengththat may pass through a guide. The guides accordingly provide “pullpoints” from which the resistance on the pull end of a cable is applied.

The winding end of each cable is wound around a coiling mechanism thatmay comprise one or two or more winding/coiling spools or reels on ashaft. A coiling gear is also provided on the shaft. The ends of theshaft are stabilized so that the shaft may rotate to allow the cable towind or unwind around the spool/reel.

The winding/coiling mechanism is connected through a pair of gears to aresistance power mechanism. The resistance power mechanism comprises aresistance power shaft and a motor. The motor may be a robotic or servomotor that provides variable and selectable resistance power to resist apulling force applied by a user to the pull end of a cable. The gearsallow a small resistance force to be generated by the motor and agreater resistance force to be applied to the user.

A computer/processor may be used to control the resistance force appliedto the cables and/or to record exercise results.
